A nurse is monitoring a client following a coronary angiography. Which of the following findings should the nurse report to the provider?

Choice A reason: Blurred vision is not an expected side effect of digoxin, but a sign of digoxin toxicity, which requires immediate medical attention.

Choice B reason: This is the correct answer because digoxin can cause hypokalemia (low potassium levels), which increases the risk of digoxin toxicity. Therefore, clients taking digoxin need to have their potassium levels monitored regularly and consume foods rich in potassium.

Choice C reason: Antacids can interfere with the absorption of digoxin and reduce its effectiveness. Clients taking digoxin should avoid taking antacids within two hours of taking the medication.

Choice D reason: Weighing oneself every other day is not related to digoxin therapy, but to fluid balance. Clients with heart failure, who are often prescribed digoxin, need to monitor their weight daily and report any significant changes to their health care provider.

Choice A reason: Difficulty swallowing is a sign of anaphylaxis, which is a severe allergic reaction that can cause swelling of the throat and tongue, leading to airway obstruction and respiratory distress.

Choice B reason: Petechial rash on the abdomen is not a sign of anaphylaxis, but rather a sign of thrombocytopenia, which is a low platelet count that can cause bleeding under the skin.

Choice C reason: Hypertension is not a sign of anaphylaxis, but rather a sign of high blood pressure, which can be caused by various factors such as stress, pain, or kidney disease.

Choice D reason: Bilateral tinnitus is not a sign of anaphylaxis, but rather a sign of hearing loss or damage, which can be caused by exposure to loud noise, ear infection, or medication side effects.
